I.D. Industrial Monitors e’ in grado di fornire monitor
CGA compatibili con praticamente tutti i modelli presenti sul
mercato.
Lo
standard CGA rappresentava un notevole sviluppo rispetto all'MDA.
Gestiva lo schermo a colori e gestiva lo schermo con i pixel,
potendo quindi lavorare con la grafica. Si potevano gestire
16 colori (4 alla volta!) con una risoluzione di 320 x 200 pixels
oppure nella modalità avanzata 2 soli colori ma con una
risoluzione ampliata di 6400 x 200.
Monitors standard CGA
I.D. Industrial Monitors offers CGA monitors that
are compatible with most models currently available on the market.
CGA
Color Graphics Adapter
Videotype: TTL, 16 colors.
AKA: IBM RGBI
A few months after the release of the MDA, the CGA adapter came
out. It worked with an RGB monitor and worked off the text-mapped
method, meaning it was capable of the pixel-by-pixel control
needed for graphics. It could also do 16 colors, 4 at a time,
on a 320 x 200 display. The pixels are quite large and the resolution
was bad, but it could do graphics. CGA offered a high-resolution
mode of 640 x 200, but then it could only do two colors. Besides
its limitations, this card remained very common for quite a
while. It had a couple annoyances, which were flicker and snow.
By snow, I mean one would sometimes get random dots on the screen.
CGA
uses a digital signal, referred to as TTL (Transistor-transistor
Logic), for the transmission of its video signal. TTL is a signal
that operates on a on or off state only, thus limiting the amount
of displayable colors. Intensity bits are used to expand available
colors up to four times the original amount. Commonly used in
low resolution computers ( Thanks to MonitorWorld)
